Wireless Energy Transfer with Negative Index Material

Abstract

Embodiments of the invention disclose a system configured to exchange energy wirelessly. The system includes a structure configured to exchange the energy wirelessly via a coupling of evanescent waves, wherein the structure is electromagnetic (EM) and non-radiative, and wherein the structure generates an EM near-field in response to receiving the energy; and a negative index material (NIM) arranged within the EM near-field such that the coupling is enhanced.

Benefits of technology

[0012]Embodiments of the invention are based on the realization that evanescent wave coupling is enhanced by arranging one or m

Problems solved by technology

To optimize the energy, a distance between the source and the sink should be as small as possible, because over greater distances the induction method is highly ineffective.

It is a challenge to enhance the coupling.
